Immediate Effects of Transcutaneous Electrical Nerve Stimulation on Pain and Physical Performance in Individuals With Preradiographic Knee Osteoarthritis: A Randomized Controlled Trial

Abstract

To investigate the effect of transcutaneous electrical nerve stimulation (TENS) on knee pain and comprehensive physical function in preradiographic knee osteoarthritis. Design: A single, participant-blinded, randomized controlled trial (RCT) with pre-post design. Setting: University research laboratory. Participants: Patients with knee pain belonging to KellgreneLawrence grade 0 or 1 (NZ50; aged 50-69y) were randomly assigned to the TENS (nZ25) and sham-TENS groups (nZ25). Interventions: All participants wore the TENS device under the patella of the symptomatic knee. After measurement, the TENS devices in the TENS group were turned on, and those in the sham-TENS group were not connected. Main Outcome Measures: The primary outcome measures included the stair climb test, timed Up and Go (TUG) test, 6-minute walk test (6MWT), and knee pain evaluated using the visual analog scale (VAS) for stair climb test, TUG test, and 6MWT. Secondary outcomes included knee extensor strengths and the 2-step test and stand-up test from the locomotive syndrome risk test. Results: Multiple regression analysis revealed that TENS intervention significantly improved the walk distance and VAS score of the 6MWT, after adjusting for premeasurement data (distance; PZ.015, VAS; PZ.030). Conclusions: Use of TENS improved the VAS score for pain and the distance walked in the 6MWT for individuals with KellgreneLawrence grade 0 or 1 of the knee. Thus, TENS may be effective for long-distance walking in patients with preradiographic knee osteoarthritis.

Comparative Effectiveness of Focused Extracorporeal versus Radial Extracorporeal Shockwave Therapy for Knee Osteoarthritis—Randomized Controlled Study

“…Sample-size calculations were based on detecting a mean difference of 2 cm minimal clinically important difference (MCID) on a 10 cm VAS between the two groups with a standard deviation (SD) of 2 cm, which was adjusted based on the results of previous studies [ 22 , 31 ]. Additional parameters used for the sample calculation were a two-tailed test, an alpha level of 0.05, a desired power of 80%, and a dropout rate of 20%.…”

Effects of transcutaneous electrical nerve stimulation (TENS) in people with knee osteoarthritis: A systematic review and meta-analysis

“…After screening of the titles, abstracts, and reference lists, 127 potentially relevant full papers were retrieved. After screening the full papers, 98 papers failed to meet the inclusion criteria; therefore, 29 studies 8–10,19–44 were included in this systematic review. Figure 1 outlines the flow of papers through the review.…”

“…Considering that we followed PRISMA statement and Cochrane guidelines, applied a comprehensive search strategy, performed a meta-analysis, and evaluated the quality of evidence according to Recommendations Assessment, Development and Evaluations approach, this review might provide up-to-date clinical practice recommendations for the treatment of patients with KOA using TENS. Compared with previous reviews, our review includes more studies 8–10,21,32,34,40,41,45 but we do not deny the possibility of omission of identify one or more relevant studies. Although with high heterogeneity and low level of evidence, we conduct the same conclusion with previous review 46 in the effect of pain relief with regard to TENS.…”

Análise dos recursos terapêuticos em pacientes idosos com osteoartrite do joelho: revisão de literatura

“…Já Almeida et al (2016), explica que os mesmos recursos trazem resultados significativos na melhora da dor e amplitude de movimento do joelho. Shimoura et al (2019), contribui para esses argumentos citando como benefício destes recursos, a melhora da caminhada. Yamada et al (2016), afirma que o treino de marcha e equilíbrio traz efeitos positivos na dor, força, qualidade de vida.…”
